as we look to the white house, we sure hope that they are getting something done, the fiscal cliff meeting at the white house right now. what were the mechanics of rushing the deal through congress and getting it passed into law? what would that look like in four days? lisa desjardins joins us now. what will it look like? >> well, there is a couple of possibilities, don. one is that they take sort of the remnants of one of the bills that passed the house or the senate and they just change it. they add whatever is in this deal to it. they have a whole bunch of vehicles that are possible for that. one sticking point, because this deal would most likely deal with taxes, there is a rule in the constitution that is has been interpreted by most every side to determine it has to begin in the house, revenue measures begin in the house. they need a bill that starts in the house, okay, they have a lot to do that. then the trick is making sure they have the votes. i think if we see anything come out of tonight's meeting, anything substantial, that's what is going to happen this next day and a half. l
